fop weblogic jar conflict

[tosswang]

hi,all

This is what I have:

-jdk-1.6、 -docx4j-nightly-20110710.jar、linux。

I get error the issue org.docx4j.openpackaging.exceptions.Docx4JException: FOP issues when i convert docx to pdf,but when the program run in windows ,i can get right result,how can i resolve this issue?

i really appreciate if someone could point to the problem.
Thank you in advance!

Please post:
1. full stack trace
2. sample docx exhibiting the problem

Nobody can help you without that basic information.

When you set logging on the PDF output to debug level, you will see the intermediate XSL FO (assuming processing gets that far). Is this generated? Is it the same on both platforms?

Is your fop font cache corrupt? Try deleting .fop/fop-fonts.cache

hi,jason:
i know the reason of the issue occur,when i convert docx to pdf ,some jar is in conflict with the jar of weblogic10.3.
our web server is weblogic10.3,below are conflict jar:

xalan-2.7.0.jar
xercesImpl-2.7.1.jar
xml-apis-1.3.04.jar

thank you again

Weblogic server libraries (and their dependencies) are always "a bit" outdated. Try to make out the versions that come with WLS and remove those described as docx4j dependencies. When building with maven, you can add the weblogic jars as "provided" dependencies and explicitly exclude the docx4j dependencies for your client. Using ant, you need to provide a custom build path modelling this (and most probably use the ant version that comes with your WLS in bea\modules\...).

If compiling or running does not work, try to make out the concrete versions of the dependencies replaced and come back with that list.

[Jarey]

I think i got the same problem described. I got conflict jars too in this version of weblogic, and then materialized in a ClassNotFound exception during docx to pdf conversion.

Keep looking for a solution, if i found one i will post on my thread and here.

Kind regards.
